in Vertical Bearings, of which the follow--` ing is a specification.

rlhe object of this invention is toproduce a vertical shaft bearing having features of novelty and advantage, and more particularly-l to provide `va bearing of substantial length and stiffness and an oiling device therefor.

The figure of the drawings represents an tical section. I

a denotes the shaft, b the housing, c the main bearing suitably supported in the housing, al, an oil reservoir in the bottom of the housing.

c isa hood supported on the lower end of the bearing and ,within which fits u bushing f which is secured to and rotates with the shaft a and has on its exterior sul-farel spiral grooves g; this bushing is recessed on its underside as indicated at z., to forma space to receive a sleeve i projecting upwardly from the bottom of the housing above the oil level which is indicated by the line c to prevent the escape of the oil from the housing. Above the bushing fis an oilpressure chamber Z the outlet from which is throughthe bearing. As-the shaft rotates the bushing f acts as a ump to feed the oil up into the chamberli from which its only outlet' is through the bearing, escaping at the upper end and returning to'the oil reservoir `by gravity through suitable passages illustrated.

This invention finds its greatest utility in connection with bearings located along the length of a shaft or spindle,l the shaft pass-v ing through the housing, and is particularly adapted for use for lubrication ofturbine shafts i which require veryl rigid bearings, owing to the are subjected.

Patentedtlct. 19, 1915.

Although l have shown a plain bearing in the illustration of my invention it will be readily apparent that the structure is equally as useful With othertypes of bearings.

I claim as my invention:

l. ln a vertical bearing, a housing, a bearing mounted therein, a shaft supported in .said bearing and extending through the housing, an oil reservoir at the lower part of the housing, an oil pump in said reservoir, and a pressure chamber having its outlet through said bearing and to which -said pump delivers oil under pressure.

2.. In a vertical bearing, a housing, a bearing mounted therein, a shaft supported in said bearing and extending through the housing, an oil reservoir at the bottom of` the housing, an oil chamber below said bearing and having its outlet therethrough,.and an oil pump located between said reservoir and chamber and adapted-to deliver oil under pressure from the former to the latter.

' 3. In a vertical bearing, a housing, a bearing mounted therein, a shaft supported in said bearing and extending through said housing, an annular oil reservoir at the lower part of the housing surrounding the shaft, a hood secured to said bearing,.a bushing secured to and rotatable with sald shaft and closely fitting within said hood, andan oil' chamber located between said bushmg and bearing and having its outlet through the latter, said bushing having spirally ar-4 ranged grooves in its exterior surface.

4. The combination ina vertical bearing withl a housing, a bearing located therein, and a shaft supported by the bearing and extending through the housing, of an annular oil reservoir located *below the housing and surrounding the shaft, the inner wall of said reservoir being adjacent toy said shaft, a bushing secured ,to said shaft and recessedto fit over the inner wall of sald reservoir, a stationary hood within saidI housing within which said bushing fits closely, and a chamber formed in part by said hood beneath andghaving its outlet bushing being spirally grooved to act as a pump to raise the oil from 4Seidl reservoir to said chamber.

5. In a vertical bearing, lubricator, (the combination With-5a shaft, a bearing therefor and a lubricant reservoir located underneath the bearing and surrounding the shaft', of a force pump With its inlet immersed in the lubricant in said reservoir, and its outlet at said bearing whereby lu- 10 brcant is forced through said bearing under pressure.
